Meanwhile, Falcon 9 and Falcon Heavy have made numerous successful and commercial launches and landings.
Also consider that it took NASA about 9 years to fully develop the Space Shuttle from ground up and they didn't lose a single vehicle during testing - 50 years ago!
This is not accurate: reusable orbital first stages is a SpaceX first, and the cost savings it yielded enabled Starlink, which is another SpaceX first (high speed, low-latency, low-altitude LEO satellite internet).
And how is it questionable? They've got the cheapest (for their class) launch prices in the world.
Elon says stupid things sometimes, but I would rather have most of the time, than more stupid manager talk from our German companies with their 'electrified intelligence' and AI in our dashboards (because they bind a GPS coordinate to a setting like Tesla).
Anyway, I really just wanted to point out that 50 years ago it was apparently possible to develop spaceships in less time without a "move fast and break things" approach.
F9 is also incredible and has made the impossible possible... and Starlink is one instance of that, which also exists and is usable.
You can't really highlight his failures without also giving credit where credit is due to his (and his organizations') successes.
I'm really curious how he gets such smart and talented people to work at his companies.
